UK Prime Minister David Cameron has been under mounting pressure since his father, Ian Cameron, was identified as a client of a Panamanian law firm that specializes in helping the wealthy to reduce their tax burdens by creating off shore investments and having offshore accounts in reports sparked by Panama Papers leaks.
The prime minister initially refused to say whether he had a stake in Blairmore Holdings, an offshore firm established by his father, before acknowledging he had sold his shares in it shortly before he was elected as Prime minister in 2010.
